Modulator
The modulator uses an indirect I/Q modulator architecture that is ideal for multiband operation. The IF
modulation improves EVM effects due to improved carrier feedthrough. The series transmit IF filters allow
improved wideband noise, which enables duplexer removal. The I/Q modulator requires no amplitude or phase
calibration to achieve high phase accuracy. The modulator can be altered between GSM900 transmit mode (TX
IF = 270 MHz) and GSM1800/1900 transmit mode (TX IF = 180 MHz) by the band bit setting in the TR register.
Table 8. Modulator Performance
VDD = 2.7 V; TA = 25 °C ± 3 °C. IQ common mode = 1.6 V; input differential signal = 1.0 Vp-p.
